Dr. Jens Wiesner: Extremely fast, reliable and assertive. He excels in international matters in particular due to his excellent international experience. He always remains in control of the mandate and maintains an overview for his client, even in the case of extremely complex contract structures and with many parties involved. My favorite for international business.

Jens is specialised in national and international finance law including the management of litigation. In addition to general advice, a focus of his practice is on the legal support of complex acquisition financing, real estate financing and project financing, acting on behalf of either the bank or the investor. Jens also advises on the areas of corporate restructuring and reorganisation.
